They say that necessity is the mother of invention. Blu-ray have been out of the need to provide a cost-effective device for playing high definition content developed. Before development, the devices proved to be highly inefficient and cumbersome. started after the development of Blu-diode laser, a project called "Blue DVR has been at the center of which was the development of rewritable discs. These records would eventually be convertedto be "Blu-ray. The first Blu-ray have been made public, in use in Japan only.
